ROCK BOLTS

POINT ANCHORED FRICTION LOK •

Standard 47mm Friction Lok Bolt installed using percussion. The slotted tube provides both radial and axial restraint to rock movement

•

Bolt has full 180kN capacity in all ground conditions

•

Easily installed in very poor ground

•

A radial crimp is located at the tail of the Friction Lok Bolt, housing a Mechanical Point Anchor

•

The Mechanical Point Anchor has a hex drive which locates into drill/dolly drive assembly when the bolt is mounted onto the drill boom

•

Once the Friction Lok is installed, left hand rotation is applied to the Mechanical Point anchor, actuating the drive and expanding the bolt tail

•

Once expanded, the Mechanical Point Anchor has a non-seizure load of 240kN, exceeding the Friction Bolt UTS

•

Simple, efficient and low cost

•

Available in black or hot dipped galvanised

ROCK BOLTS

M24 TORQUE TENSION Features

The “X” grade steel used by Jennmar has superior toughness and ductility through the use of grain refining alloys. The Jennmar “X” grade bolts should provide better performance in mines where Stress Corrosion Cracking is evident and also in areas of high localised horizontal stresses.

•

The JX rock bolt profile provides superior load transfer characteristics using the unique “J” bar pattern.

•

Recommended for drill hole sizes 27 – 28mm diameter without mixing devices or 35-40mm with resin mixing devices

•

M24 couplers, 35mm diameter are available for use with torque tension bolts

•

Various roll pin break-out torque ranges available

•

Available as galvanised

•

EYE BOLTS & HANGERS

‘CLIP UP’ HOOK •

The Sorrich “Clip Up” hook has been developed for underground application and designed to hold four inch (110mm) Polyurethene Pipe

•

Load rated hanger to 800kg WLL

•

The diameter of each separate hook is 120mm, allowing enough room to easily slide “poly” inside the circumference of each hook and just enough room for the poly pipe to be held firm inside the hook to reduce movement. Each 4-inch poly line are then locked in place by our patented locking system, which integrates with the Minsup clip for quick and easy installation. The “Clip Up” is made from 6mm galvanised mild steel for strength and to prevent rusting in normal underground environments

•

The top is an open 2-inch (66mm) hook for possible temporary 2-inch poly pipe or for use with power or pump cable, which prevents tangles amongst other lines.

•

The backside of the hook has been designed to be capable of clipping back to the mesh or rock bolts with a simple “D” shackle when hanging in the ‘’shoulders”.

•

This product is the only one of its kind on the market and it is the safest, fastest and neatest way to install poly pipe.
